Date filtering from days in months instead of a set date

[paulfink]

My idea is to implement a feature that instead of advanced filtering from a set date e.g Jan 31 - March 31, you can filter from the 1st of 2 months ago to today and that will stay and update as the months go by so no matter what time of the year you look at the data, it will always show the 1st of the previous 2 months.

I know there is DAX for this but for new users like myself, i have been using power bi for work for 3 months now, it is still a challenge to figure this out.

It is on the same principle as the relative data filter, it could be a filter type called advanced relative data filtering. Picking what days and how many months it will filter by.
